I don't know why I still keep this thing

I find myself at the trough of depression again. This happens a lot, but it still sucks when it does. It's all sorts of stuff that brings me down: grades, girls, mainly girls. I have no idea why, but for some reason I just can't be happy alone. I've been trying like crazy to find someone, and everyone says it'll happen when I stop looking. I can't stop looking! I'm constantly subconsciously analyzing almost every girl I meet. It really bothers me seeing other people in a relationship together, because don't have that. There's almost no one close to me that I can connect with. Also, whenever I try and get close to a girl, she declares us good friends. I'm getting really tired of having exclusively male friends. I love my friends, but I don't have any friends that are girls.

Friends

A friend is dating a dick. It sucks! What do you do? Tell them about it. That's all you've got. No matter how good of friends you are, they'll side with their phallic significant other. It doesn't matter what you say, because your friendship is more important than a final stand, a me or them deal. There's no way you can tell them that you won't be friends anymore if they keep dating that person, that would just show them how unimportantly serious you are. So you tell them all the reasons that person sucks, and they won't believe half of it. The half they do believe, they'll defend. It's like talking to a brick wall; you're going to get nowhere. So they go o dating this penis and when they're not so hurt they question the relationship, it's the best it's ever been. And the whole time you want to tell your friend that they should dump this guy, it's only because you think you could fill the spot ten times better...
